HEALTH CONDITION OF VIMBA BREAM, VIMBA VIMBA (L.), FROM THE BARYCZ RIVER

Mariusz Kleszcz, Wiktor Niemczuk

ABSTRACT. In May 2009 parasitic and histoenzymology studies were performed on 22 females and males of vimba bream caught in the Barycz River as part of a restoration program. In a few of the specimens pox-like pathology was noted on the skin. Examinations revealed that these were either caused by a pox virus or the cercariae of Diplostomum sp. Nine genera of parasite were noted to occur in the fish: Myxobolus, Trichodina, Chilodonella, Daktylogyrus, Gyrodactylus, Diplostomum, Posthodiplostomum, Asymphylodora, and Acanthocephalus. Despite the occurrence of various parasites and of localized histoenzymological pathology, the health condition of the specimens of vimba bream examined from the Barycz River was generally good.
